Function and significance of skateboard chassis

Skateboard chassis

The reason why skateboard chassis attracts attention is largely due to the development of wire-controlled technology and the fiery heat of new energy vehicles.

Steering-by-wire technology replaced the steering column and mechanical braking system, and the battery replaced the engine. Hundreds of parts on the traditional chassis can be integrated into three modules of 10 parts.

The skateboard chassis can be simply described as "non-loaded body structure+steer-by-wire/brake system+battery pack and chassis integration".

1, structure of non-load-bearing main body

Therefore, the vehicle model can be developed relatively simply and independently, because there is no need to bear the weight of the vehicle model.

In 2002, GM tried it on a concept car.

Leave ten connection points between the car model and the chassis, so that different cars can be matched to the same chassis.

2. Wired transmission control system

You can cancel the "hard mechanical connection" between the upper house and the lower house, because the mechanical connection such as steering column is cancelled, users will feel that the space in the upper house is unprecedented and the vehicle design can be innovative and diverse.

The bulky battery pack originally needs a high-strength shell to ensure safety, and the frame under the non-loaded body structure also needs high strength. The integration of the two is similar to killing two birds with one stone, almost killing two birds with one stone.

3. Integration of battery pack and chassis

Many people may still have some doubts. What is the biggest difference between the skateboard chassis and the current pure electric platform? Li Peng, the founder of Youpao Technology, once said, "The skateboard chassis has a clear line in technology, that is, whether it supports the development of the upper and lower parts."

The skateboard chassis will integrate all the capability modules of the intelligent electric vehicle, including power, braking, steering, thermal management, three electric and automatic driving, and it needs complete wire control, so as to decouple the upper and lower car bodies.
